i purchased the center to see if it would improve dialogue during movies that the Onkyo speaker did not. Matched with the Onkyo TX SR707 this center did improve dialogue, but i am still skeptical that the rest of the Klipsch 52 series speakers will be much of an improvement vs the Onkyo set. Not feeling a full sound but that could be a result of mismatched. The Klipsch don't need much power and Audyssey setup with mismatch was wild, so i may just have to plunge and see what happens. Overstock is always good price and servic e.
